Key Ocarina of Time cast members Sheik, Ruto, and Darunia have been confirmed by Famitsu as playable characters in the upcoming Wii U title, Hyrule Warriors.
Sheik, of course, is well-known as Zelda’s alter ego and has featured prominently in the Smash Bros. series, but these will be the first playable appearances for the other newly-confirmed battlers. Ruto is Ocarina of Time’s Princess of the Zoras, while Darunia is the leader of the Gorons. There are currently scant details regarding the characters’ weapons or unique play characteristics, though this info will likely roll out in the coming days.
There is a bit of news in the Famitsu article regarding the return of Golden Skulltulas as collectibles in the new game, though specifics regarding their acquisition or effects remain unknown.
Hyrule Warriors releases in Japan on August 14, then in Europe and America on September 19 and 26, respectively. Check out the latest Japanese gameplay trailer, featuring Link wielding the Power Gloves and Ball & Chain, below.
